UNITED STATES WILLIAM K. EARLE, 0F OCEAN PARK, CALIFORNIA.

CASEMENT-ADJ'USTER.

Application filed July 19,

To all whom it may concern Be it known that I, WILLIAM K. EARLE, a citizen of the United States, residing at Ocean Park, in the county of Los Angeles and State of California, have invented a new and useful Casement-Adjuster, of which the following is a specification.

My invention relates to the art of mounting casement windows and similar swinging windows or doors, being more particularly a device by means of which the easement may be held in different positions.

One of the principal objects of this device is to produce an adjuster which ma be mounted upon and form a part of the huge, such construction bein of simple and economic form and of sue a nature that it is not necessary to mar the casement or have any unwieldy device extending into the room.

Other objects and advantages will be made evident hereinafter from the following specification.

Referring to the drawings, which are for illustrative purposes only,

Figure 1 is a perspective view of a hinge embodying a form of my invention.

Fig. 2 is a plan view partially in section showing the manner in which the casement is mounted; and,

Fig. 3 is a perspective view of the curved rod forming a part of the device.

The hinge consists of a leaf 11 and a leaf 12 pivotally connected together in the usual fashion by means of a pintle 13. The leaf 11 may be termed a fixed leaf, being pro vided with suitable screw holes 14 arranged to receive screws indicated in dotted lines at 15 in Fig. 2, which secure the leaf 11 to the window frame 16. The leaf 12 may be termed the swinging leaf and is provided with screw holes 17 which are arranged to receive screws 18 indicated in dotted lines in Fig. 2, which screws 18 extend into the casement indicated at 19 and secure the swinging leaf 12 to the easement.

20 indicates a round rod bent in circular form, one end of the rod being shouldered as indicated at 21 and terminating in a reduced portion 22 which is exteriorly threaded to receive a nut 23. The reduced portion 22 of the rod extends through a hole or perforation 24 formed in the leaf 11, the shoulder 21 being tightened against the inner face of the leaf 11 by means of the nut 23 thereby rigidly mountindg the rod upon the leaf. The rod 20 exten s through an open- Specification of Letters Patent.

ing or perforation 25 in the leaf 12, and when the rod 20 isso mounted the rod extends in a circular manner partially around the pintle 18, but is so arranged that the rod is eccentric with relation to the pivotal axis of the hinge, that is, the pintle 13.

It is understood that while the rod 20 is shown as a round rod that the same may be made in different cross-sectional form, in which case the opening or perforation 25 is correspondingly shaped to receive the rod.

The operation of the adjuster is as follows: I

When the easement is closed as shown in full line position in Fig. 2 it is understood that any suitable form of fastening device, such as a latch, (not shown) maybe used for holding the casement in such position, but if it is desired to place the casement in any open position the easement is moved to such desired position andin so doing the opening 25 in the leaf 12 moving in a circular path concentric with the pivotal axis of the hinge springs the rod thereby causing a binding action between the rod and the inner edge of the perforation 25, such binding or frictional contact between the rod and the swinging leaf 12 being suflicient to hold the casement in any open position in which the same may be placed. This binding action is caused by reason of the perforation inthe swinging leaf moving in a circular path about the pintle and as the rod is mounted eccentric with relation to the pintle the rod is sprung outwardly thereby binding in the perforation.

I claim as my invention 1. A casement adjuster comprising two members adapted to'be secured to the casement and casement frame respectively; a pintle connecting said members; and an eccentrically shaped spring rod secured at one end in one of said members and frictionally engaging the other of said members.

2. A casement adjuster comprising two members adapted to be secured to the case ment and casement frame respectively; a pintle connecting said members; and an eccentrically shaped spring rod secured at one end in one of said members and passing through a hole in and frictionally engaging the other of said members.

In testimony whereof, I have hereunto set Patented May 17, 1921.1

my hand at Los Angeles, California, this 14th day of July, 1919.

WILLIAM K. EARLE.
